OK - let's be clear we are talking the same thing here.
Basic Upset recovery training has been in place for some years now in many jurisdictions, generally post AF447, in some cases earlier. This can be done in most sims. It does not cover the full stall.
New changes being implemented include an extended envelope training course in full stall /stick pusher recovery, full upset (eg 120 deg+ Aob recovery) and a couple of days classroom theory. It's not a check per se, it's training and will be mandatory for all existing pilots and a refresher involving this each year. And the UPRT/EET will become part of the type rating. SFIs will need specific training to conduct the course and can only be done in the upgraded sim. There is a massive emphasis on the dangers of existing negative training with existing simulator training.
I had a short session a little while ago in the sim with the FAA guys going over this.
